NASA's Cassini spacecraft captured images of a revolving mass of gas in the atmosphere over Titan's southern pole. This odd cloud group completed a full rotation in 9 hours – quicker that the moon's 16-day rotation period.

This up close and personal look at the gas giants and their moons was stitched together by Sander van den Berg using imagery captured by NASA's Voyager and Cassini spacecrafts. Van den Berg named the black and white piece 'Outer Space'.

This cool space wallpaper shows Cassini spacecraft looks toward the dark side of Saturn's largest moon as a circle of light is produced by sunlight scattering through the periphery of Titan's atmosphere.
